GATE-HINGE.

EPBCIPICATION forming part of Letters Patent No. 336,469, dated February16, 1886.

Application filed October]3,1885. Serial No. 179,801.. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES BORNARTH, a citizen of the United States,and a resident of Shakopee, in the county of Scott and State ofMinnesota, have invented certain new and use ful Improvements inGate-Hinges, of which the following is a description.

The invention consists in certain novel elements and combinations ofelements in the supporting mechanism of a gate or of a door, wherebysuch gate or door is made movable upon its hinge-rod, either in avertical or in a horizontal plane, and whereby when closed the same islocked against movement in a horizontal plane.

It consists, also, in the combination, with a locking-hinge of thecharacter described, of novel locking appliances upon the latching ormeeting extremity of the gate and upon its latching-post, or upon eachof two oppositely hinged gates.

In the drawings, Figure 1 is a view in side elevation of a portion of agate and its hingepost, showing my improved means for hinging andlocking applied thereto, the gate being in its hinged and lockedposition. Fig. 2 is a horizontal section on thelinew x of Fig. 1. Fig. 3is a view in side elevation of a double gate and its posts, one of thegates being elevated and unlocked and in position to be swung in ahorizontal plane upon its hingerod. Fig. 4 is a top plan view showingthe improvements as applied to a single gate and its latch-post, andshowing also half-hinges as applied to the face instead of to the end ofthe gate and of the part to which it is latched. Fig. 5 is a plan Viewshowing, upon an enlarged scale, the modified form of half-hinges whichis represented in Fig. 4. Fig. 6 is a plan view of another modification,in which the central meeting portions of the two hinge sections are ofangular form.

The grooved half-hinges a-two or more in number-are secured to thegate-post A by throughbolts a or by other suitable means. A hinge-rod,A, preferably extending through the post A, is secured to such post at apoint below the lowermost hinge and at a point above the topmost hinge,and this rod will be steadied and braced by an eyebolt, a, through whichit extends, and which, being secured within the post, constitutes asupport for the gate. The half-hinges I), having by their passage [2first been sleeved upon the hinge-rod, will be made fast to the gate B,and a suitable line, B, of rope or chain, attached to the upright B ofthe gate, will be passed over pulleys of a, which have their bearingsupon one or more arms or cross-pieces, A, upon the post A, and will beconnected to a counter-weight, B

It will be seen that the shoulders b b of the half-hinge b upon the gateabut squarely against the flat ends a a of the jaws a a of thehalf-hinge a, and thus prevent horizontal movement of the gate, and itwill be apparent that the function of these parts is unaffected by theconfiguration of the groove 64 and the corresponding projection upon thepart b, so that it is immaterial whether these parts be curved, as inFig. 2 and in Figs. 4 and 5, angular, as in Fig. 6, or of some otherform.

Upon the meeting faces of the uprights B of the gates, as in Fig. 3, orupon such upright and its latch-post O, as in Fig. 4, will be securedsimilar half-hinges, a and b, which as thus attached will constitutelocking appliances, and these will act in conjunction to lock the gateor gates in position at the outer or unhingedextremity of the same.

From the foregoing it will be understood that so long as the twohalf-hinges are in' contact the gate will be immovably locked at eachextremity thereof, and that it must be elevated bodily until thehalf-hinge b is above the plane of the upper extremity of the coincidenthalfhinge a before it can be moved horizontally upon its hinge-rod orpivotal bearing A.

It will be apparent that the elevating-line, instead of being connectedto the hinge end of the gate, as already described, might be ap plied atthe center thereof, running in antifriction rollers upon a cross-beamresting upon the two opposite posts of the gateway, as represented indotted lines in Fig. 3. I do not, however, limit myself to lines andcounterweights as means for elevating the gate, as any other well-knownmeans may be employed.

Under the construction represented in Fig. 3 the gate may be elevateduntil its lower hinge is brought into contact with the bolt a, which ispreferably contiguous to the upper hinge-sections, thus enabling thegate to be readily opened when heavy snows or other I obstacles obstructits movement in its lower position.

Any suitable locking device may be applied to prevent the gate frombeing raised and thrown open by unauthorized persons.

It is obvious that the groove or recesss might be provided in thehalf-hinge upon the gate outside the perforation therein, and that theprojection might be formed upon the halfhinge of the post withoutaifecting the principle of the operation.

Having described my invention, I claim 1. The combination, with agate-post which is provided with a hinge-rod and with recessedhalf-hinges, of a gate which is provided with corresponding half-hinges,each of which has a perforation which receives the hinged-0d and aprojection which engages the recessed halt hinge upon the gate-post, thehalf-hinges having coincident flat bearings, whereby when any portion ofsuch half-hinges are in the same horizontal plane the gate is lockedagainst rotary movement upon its hinge-rod.

2. The combination of a gate-post which is provided with recessedhalf-hinges, with an elevatable gate which has projecting halfhingeswhich are sleeved upon a vertical hingerod, the projections engaging therecesses continuously from top to bottom thereof, whereby the gate islocked against movement in a horizontal plane whenever any portion ofone of the half-hinges is opposite to any portion of another half-hinge.

3. A perpendioularly-elevatable gate which upon each end isprovided withlooking halfhinges, in combination with gate posts or uprightsoppositethe ends of such gate, which are provided with corresponding lockinghalfhinges, as described, whereby'when the gate has been loweredperpendicularly into its closed position it is at each end lockedagainst movement in a horizontal plane.

4. The combination of a gate-post which is provided with a hingerod andwith recessed locking half-hinges which have flat bearingsurfaces, agate post or upright which is un provided with a hinge-rod and isprovided with recessed locking half-hinges which have fiatbearingsurfaccs, and a perpendicularlyadjustable gate which upon eachend has locking half-hinges which are provided with projections and withflat bGZLTfiDg-SUIfitCES- which correspond with the recessed and flatsurfaces of the locking half-hinges upon the gate posts or uprights,whereby when the gate is in its closed position it is at each end lockedagainst movement in a horizontal plane.

5. The combination, with a gatepost which is provided with averticalhinge-rod and with recessed locking projections, of a gate which isprovided with perforated locking projections which are sleeved upon thehinge-rod and which are iusertible in a vertical plane within therecessed projections upon the gatepost.
